Line
an 8x8" pan with parchment paper and preheat oven to 350º. Gently mix
malted milk powder, peanut butter cups, and pretzels into the cookie
dough and press into pan. Bake for 20 minutes, or until edges begin to
brown slightly.

In a microwave-safe bowl, combine (unwrapped)
caramels with 1 Tbsp. water or milk and microwave in one-minute
intervals until melted and smooth. Pour over cookie mixture.

Let
this cool several hours or overnight. Once cooled, melt chocolate chips
(and cream, if desired) in microwave, stirring every 30 seconds or so
until shiny and smooth. Pour this over top of the caramel. Put in the
fridge to cool, then cut into squares.
